Conrad Johnson PV-10A mod experiences?


Has anyone had experience performing a mod on the CJ PV-10A? I'm fond of this preamp, it has that wonderful tube openness and sweetness for harmonics. However over the past 6 months as I've delved into PC audio and DAC improvements, I've come to realize two things about it

1) its slow on transients
2) its dynamically compressed.

I'm using Mullard NOS tubes throughout as these seem wonderfully detailed with excellent base.

Since the preamp is built like an engineering prototype (overbuilt)my gut hunch is that some caps have aged (circa 1993)and need replacement, specifically the white CJ caps
and am thinking about replacing them first with Multicaps.

Wondering if anyone has experience trying to revitalize a PV 10A?

I hadn't expected immediate improvement using the VCaps, noe the less I got one. While theres still a long break in time ahead, Im finding on every piece that has percussive bass there is much deeper bass. Bass drum is now a thunderous joy to listen to versus a polite whack.
did any of you replace the caps and resistors yourself.. if so how was it done..............thanks
resistors are all original. Output section of pre and phono has 2 2uf PPE Solens which I replaced some while ago
with the SE Solens series
also replaced the stock electrolytics on power supply section with Nichicon fine gold caps but that didn't seem to cause a noticeable change
ok so the upgrade bug is hard to stop. I've now upgraded in the pre mains section the 13.5 uf solens to 2x 6.8 uf Mundor Supremes and replaced the 10uf Solens with same in Mundorf Supreme. A wonderful improvement, gobs of tone color detail, accompanying players get the same clarity as the lead line. At first listen I was worried I'd just put in a high pass filter... no cymbal sheen. Now after 25 hours of play, all has evened out and Mundorf Supreme has my utmost respect for musicality at an affordable price.
